FLAT- S UPPORTING DEVICE FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 422,849, dated March 4,1890. Application filed September 20, 1889. Serial No. 324,632. (Nomodel.)

To aZ Z whom it may concern.-

Be it known that I, CYRUS A. TAFT, of Whitlnsville, in the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Flat-Supporting De vices for arding-Engines; and I herebydeclare that the following is a full, clear, and exact description ofthe same, reference beng had to the accompanying drawings, forming partof this specification.

This invention has reference to improved devices for adjusting andsupporting the topflats of carding-engines; and it consists in thepeculiar and novel construction of the side frames and vertically-adjustable supporting-pins as will be more fully set forth hereinafter.

Figure 1 is a side view of part of one of the side frames of acaidingengine, showing the ends of the top-flats supported on adjustablesupporting-pins. Fig. 2 is a sectional view of one of the end frames andatop-flat, showmg, also, the adjustable support in elevation.

In the drawings, the number 4. indicates the upper part of one of thetwo side frames whereon the top-flats of a carding-engine are supported,and the main carding-cylinder revolves between the two side frames.

All the parts herein shown or described are on one end of the maincarding-cylinder; but the same parts are also used on the opposite endof the cardingcylinder.

5 indicates the top-flats,

6 is a shield secured to the side frame 4, it entering a groove in eachof the top-flats. The side frame 4t is provided with the projectingflanges 7 and 8 and the raised surface 9. These flanges form segments ofa circle, of which the center of the main carding-cylinder is thecenter. 7

The adjustable support for each top-flat consists of the conical pin 10,which enters a conical hole in the top -flat and has at its lower endthe shoulder 11. The central portion of the support is the squaresection 12, having the longitudinal slot 13, and the lower portion isformed into the screw-threaded rod 14. In the flange 7 holes aredrilled, through which the screw-threaded rod 14 passes, and a seat isformed in the flange 8 to receive the square section 12. The screw 15passes through the slot 13 and enters a tapped hole in the side frame 9,the head bearing against the outer face of the square section 12 andholding the support firmly in the seat formed in the flange 8 andagainst the face of the projection 9. The nut 16 bears against the uppersurface of the flange 7 and the nut 17 against the lower surface of theflange.

The top-flats of a carding-engine must be adjusted with great nicety tothe cardingcylinder, and when adjusted must be supported in the adjustedposition. With the improved construction herein shown and de scribed theadjustment can be made with the greatest nicety and accuracy and thesupport firmly secured against any possible derangement. By slightlyloosening the screw 15 and adjusting the nuts 16 and 17 thesupportingpin can be raised or lowered very slightly and firmly securedin the desired vertical position by screwing the nuts tightly againstthe flange 7 and then tightening the screw 15. As the seat formed in theflange 8 presents square shoulders, between which the square section 12fits with a sliding fit, the supporting-pin is firmly secured and holdsthe top-flat against the strain of the carding-cylinder, and as theseadjustable supporting-pins are placed on both sides they form a firmsupport for both ends of the top-flats. The necessary adj ustment can bemade at any time, or from time to time while the carding-engine is inoperation.

I am aware that the top-flats of carding-engines have been secured 011pins or daggers secured in and projecting radially from the side frames.I am also aware that top-flats of carding-engines have been secured onsuch pins or daggers and have been supported on screws tapped in theside frames, so that the topflats could be adjusted at each side withreference to the cylinder; and I am alsoaware that it is common incarding-engines to provide the frames on the opposite sides of thearches each with a flange concentric with the maiircylinder, havingradial holes in which the screw-threaded shanks of supporting rods aresecured by nuts turning on said shanks above and below said flanges forsupporting the card covered rolls which take the place of the ordinarytop=flats, whereby by the turning the said nuts the distance of thebearing from said flanges and the distance of the rolls from saidcylinder may be Varied.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the side frame of acarding-engine provided with the flanges 7 and 8 and the top-flats, ofsupporting-pins secured adjustably to the flange 7 and held in seatsformed in the flange 8, as described.

2. The c0mbination,with side frame 4, provided with the flanges 7 and 8,and the topfiat 5, of the adjustable support for the topflat, consistingof the pin 10, the shoulder 11, the slotted square section 12, thescrewthreaded rod 14, the nuts 16 and 17, and the screw 15, asdescribed.
